Digital to analog converter (DAC)

A digital to analog converter for converting a sequence of digital words into a corresponding analog signal, comprising:

• a thermometer code generator fed by the sequence of digital words for providing N parallel outputs, each one of the outputs having one of two discrete levels;
• an amplifier section having a plurality of N amplifiers, each one of the N amplifiers being fed by a different one of the N outputs;
• and
• a load modulation network for combing outputs of the plurality of N amplifiers producing a sequence of analog signals having levels related to the decimal values of the sequence of the digital words, including:
• a plurality of amplifier sections;
• and an interconnection network for interleaving connections between the thermometer code generator and the plurality of amplifier sections.
